Description
The Fermi Bubbles are a pair of bubble-like structures symmetric to the galactic center, which are assumed to be morphologically formed by strong energy releasing events happened million years ago. Regarding the emitted Gamma-Rays, high energy radiation processes like hadronic or leptonic emissions accompanying the outflows are responsible for the origin of the emission. As predicted by theoretical works, the difference between hadronic and leptonic emission models locates over TeV bands in the Gamma-Ray spectrum, which is luckily detectable for LHAASO and thus an interesting topic. In this talk, we are going to report the preliminary results on the observed Gamma-Ray flux upper limits with LHAASO-WCDA.
